The Errors messages in edit actions, doesn't appear - php

Question

I have my validation rules in model, and everything is fine. It validates like I want to, but in the Edit actions, although it not validates, don't show me de red error marks under textbox.
Any tip?
Thanks.
The Model Code(Model name is Safpercent):
var $validate = array(
'sequencia' => array(
'must_be_numeric' => array(
'rule' => 'Numeric',
'message' => 'Number Field: insert only numbers.'
)
),
);
View Text Box:
echo $form->input('Safpercent.sequence', array('id' => 'sequence', 'options' => $criteria, 'label' => false, 'div' => false, 'style' => 'width: 300px'));
Controller Code:
function edit($id = null) {
$criteria = $this->Safpercent->Safrequirement->find('list', array('fields' => array('Safrequirement.sequencia', 'Safrequirement.descricao'), 'conditions' => array('Safrequirement.tipo' => 'ILC')));
$this->set('criteria', $criteria);
if (!$id && empty($this->data)) {
$this->Session->setFlash(RecordNotValid, 'flash_failure');
$this->redirect(array('controller' => 'safpercents', 'action'=>'index'));
}
if (!empty($this->data)) {
$sequencia = $this->data['Safpercent']['sequencia'];
if($this->data['Safpercent']['tipo'] == ''){$tipo = 'ILC';}else{$tipo = $this->data['Safpercent']['tipo'];}
$encontro = $this->Safpercent->Safrequirement->find('all', array('conditions' => array('sequencia' => $sequencia, 'tipo' => $tipo)));
if($encontro <> array()){
if ($this->Safpercent->save($this->data)) {
$this->Session->setFlash(RecordSaved, 'flash_success');
$this->redirect(array('controller' => 'safpercents', 'action'=>'index'));
}else{
$this->Session->setFlash(RecordNotSaved, 'flash_failure');
}
}else{
$this->Session->setFlash('A Sequência que tentou Inserir não existe. Verifique a tabela de novo, por favor.');
}
}
if (empty($this->data)) {
$this->data = $this->Safpercent->read(null, $id);
$this->set('id', $id);
}
$this->set('cod_percent',$this->Safpercent->read(null, $id));
}

Answer 1

Try
debug($this->Safpercent->validationErrors)
and see if it shows any errors.

Answer 2

I see now. In your controller, you are using the sequencia field that you are validating, but not doing any validation at this stage. It passes a non-number to the find query, which then returns an error or something, and the save never gets called?
Before you do this:
$sequencia = $this->data['Safpercent']['sequencia'];
You should check that the data validates, by calling this:
$this->ModelName->set($this->data);
if ($this->ModelName->validates()) {
... //do your business here
So basically, change:
if (!empty($this->data)) {
to:
$this->Safpercent->set($this->data);
if (!empty($this->data) && $this->Safpercent->validates()) {
